COOK STOVE AND RANGE.

SPEGIFICATION forming part of Letters Patent No. 269,829, dated January 2, 1883.

Application filed July 25, 1882. (No model.)

To all whom it may concern Beit known that I, ADDIS E. CHAMBERLAIN,

ot'the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Cook Stoves and Ranges, of which the followingis a specitication.

My invention relates to cook stoves and ranges.

The main object of myinvention is'to utilize the heat which, along with the smoke, passes from the combustion -chamber, and which in ordinary cases is lost.

The principal features of my invention consist in a novel arrangement of the lines of the stove.

In theaccompanying drawings, making part of this specification, Figure 1 represents a perspective view of a cooking-range embodying my invention, the side of the stove next the observer and certain other portions, as shown, being broken away to admit of an inspection of the interior of the stove. Fig. 2 represents a vertical transverse section oi'thestove,taken at the dotted line or x of Figs. 1 and 4, the tower being omitted. Fig. 3 represents a vertical transverse section of the stove, taken at the dotted line y 1 of Figs. 1 and 4. Fig. 4. shows a vertical section of the stove, taken through its longitudinal center, those portions of the stove shown in Fig. 1 which are above the top plate and out of the plane of this section being omitted from this drawing; and Fig. 5 is a perspective view of a part of said stove, showing the mode in which a hot-air flue may be changed into a working-flue, portions of the stove being broken away to exhibit said additional flue and its connections; Fig. 6, Sheet- 3,is atop view of the stove, the top being removed and Fig. 7 is a top view of the bottom of the stove, the rest of the stove having been removed.

Aindicates the stove; B, the base or bottom plate; 0 U, the sides; D, the front end; E, the rear end, and F the top.

A fire-chamber, G, of any suitable construction, is at the front end-of the stove, and is contiguous to the forward oven, H, having front end, H, bottom H rear end,H top H, and partition H between said oven and said fire-chamber. The rear oven, 1, has a top, 1, a front, 1 a bottom, 1 and a rear end, 1*.

vertical partition J, thereby forming the side diving-fines, b b, and central flue, K, the bottom flues, d d, and the central return bottom flue, 6. Between the bottom I of oven I and base Bis fluef. Fine 0 aforesaid at rear opens into fluef. Below flue e and fora distance in fiuefthe base B has a depression, B, thus enlarging the capacity of this flue e and enabling it to readily receive and allow ot' a ready passage through it of all the heated air and smoke coming through the tines d d. (See more particularly Figs. 4, 5, and 7.) Flue f connects with flue g, formed bet-ween the back wall, I, of oven I and the rear end of the stove. This latter flue may enter directly into the smoke-discharge pipe. Thestraightdischargeflue h is formed between the top of the stove and the top of oven 1, and may open directly into the smoke-discharge pipe. The top of flue K, (see Fig. 4,) formed between the vertical portions of partitions J and between the rear wall of oven H and front wall of oven I, is in the present instance closed at the top by a suitable plate, as K, and open at bottom into flue e, and forms a hot-air chamber. It may, however, be arranged, as shown in Fig. 5, to form a part of the working-dues, and of such arrangement mention will herein be subsequently made.

A sliding damper, L, extends transversely across the stove at or about the point shown in flue h.

The mode in which the devices already described operate is ast'ollows: When thedampor L- is open the heated air and smoke pass through flue a and flue h, through the damper, into the discharge-pipe, thereby heating the top of ovens H and I. The front of oven H is heated by the fire-chamber G. Oven H is thus heated in a common manner, and oven I partially heated, sufficiently to be used as a warming-chamber.

In operating the features of my invention already described the damper L is closed, and the heated air and smoke pass through flue a, down diving-fines b, thence through fines (I, then through return-flue e, thence through flue j, under oven 1, to line g, through which latter it passes into the discharge-pipe or other intermediate passage-way arranged to receive it. The air in the perpendicular flue or chamber K is heated, and thus the ovens II and I are heated on every side, and bread can be baked simultaneously in both ovens.

Another feature of my invention consists as follows: The residue of heat remaining in the hot air and smoke after passing throughthe lines, as described, may be still further utilized by causing it to heat a boiler, as M, the presence of the diaphragm N and the preferred location of the discharge-pipe at the end M of the reservoir, as shown in Figs. 2 and 3, compelling the smoke, &c., coming by way of flue g to come into contact in fiue k with the entire bottom surface of the boiler, and the diaphragm P compels the smoke, &c., coming through flue h when the damper is open to likewise travel beneath the entire bottom of the boiler. hen desired, instead of the boiler M, a center and lids may be substituted, being preferably located at the dotted line 2 z of Fig. 4, and the usual stove utensils for cooking, &c., be heated there.

A third feature of my invention for still fun ther abstracting the heatfrom the smoke, 850., is the tower T, consisting of two tiers of chanr bers or ovens, It and S, provided with suitable doors, as It and S, the hot air and smoke from the stove heingcompelled to pass through the pipe or fine m into the flue a, interposed between the upper and lower ovens, and thence into the flue p, and thence into the dischargepipe 2, thereby warming the chambers suffi' ciently for light baking. To utilize the hot-air flue or chamber K as a workingflue, I form a horizontal tlue, XV, above oven I, as shown in Fig. 5. I connect this fine, at its rear end to the rear flue, as h, or the discharge-pipe, and the forward end of the said fine to the upper end of the line K, and place at the junction of tines K and W a damper, K for controlling the flow of gases through the last-named fines. By closing damper L and opening damper K the heated fluids will pass from the tire-chainber through flue a, fines b and (I, through flue c, and up through fines K and \V to the dis chargepipe. By closing damper L the fluids pass around the ovens in the course first described in this specification.

\Vhile the various features of my invention are preferably employed together, they may be used independently of each other, and one or more may he used, so far as applicable, in stoves of a construction different from that herein shown.

scribed, the damper L and the diaphragms I and N, for compelling the fluids to traverse the entire length of flue It, all combined substantially as and for the purposes specified.

3. In a cook stove or range, the combination of the discharge-pipe of the stove and the tower T, consisting of the double tier of ovens, line 922, interposed flue n, and fine p, substantially as and for the purposes specified.

4. In a cook stoveor range, the combination of the lines a I) d c fg h, damper L, flue K, damper K and fine \V, substantially as and for the purposes specified.

5. In a cook stove or range, the ovens II and I, tines a 71?, damper L, diaphragm P, tlucs b I]. cfg, diaphragm N, and fine It, in combination, substantially as and for the purposes specified.

6. In a cooking stove or range having two ovens, the diving-tines I), located between said ovens, in combination with the smoke-chanr ber K and lines f and g, substantially as and for the purposes specified.

7. In a cook stove or range, the combination of the discharge'flues k mat and dischargepipe I, substantially as and for the purposes specified. v

8. In a cook stove orrange havingtwo ovens, the combination of the narrow deep returnflue 0, located under the forward oven, the

wide shallow tiuef, extending under the bottom of the rear oven and connected to flue c, the damper L, and the co-operating fines for enabling the stove to be operated by a single damper, substantially as and for the purposes specified.

9. In a cook stove or range, the combination of the rear discharge-flue, k, the tines h and g, and the diaphragins I and N, for compelling the fluids to travel the entire length of said tine 7. before escaping from the stove, substair tially as and for the purposes specified.

10. In a cook-stove having two ovens, the bottom B, having the depression B, forming with partitions J the deep tine 0 under the forwar d oven and extending into the broad flat fluef under the rear oven, substantially as and for the purposes specified.
